Washington Suburban Sanitary Commission spokesman I.J. Hudson says the sinkhole is the result of a 12-inch water main break on Feb. 16.

He says a patch was made to the broken main, and a contractor was supposed to come out the next day to repair the pipe. That apparently didn't happen. Hudson says the patch failed overnight, and the road started to sink.

Crews are expected to begin repairs later Wednesday morning, but it’s unclear how long it will take to fix.
